Seismic Retrofit Measures for Highway Bridges. Volume 1: Earthquake and Structural Analysis

摘要

The primary objectives of the report are to (1) provide current information on the theory and techniques for seismic analysis of highway bridges, including background material on basic structural dynamics, (2) identify the appropriate criteria necessary to decide if a bridge needs retrofitting and the type of retrofit measures to employ, and (3) demonstrate design details and installation specifications for retrofitting existing highway bridges to minimize earthquake damage. Volume 1 includes a definition of terms, seismic risk maps, techniques and equations for the analysis of existing bridges subject to earthquake loadings, and criteria for determining if a bridge warrants retrofitting.
